AI Technical Summary
Traditional current/voltage transformers are difficult to adapt to the measurement requirements of wide dynamic range, fast time-varying and strong random signals in new power systems, resulting in inaccurate measurements and difficulty in identifying operating status.
A voltage and current combined sensing device based on solid-state spin quantum sensing is adopted, which includes an insulator, a primary conductor, a shielding unit, an electric field measurement unit, and a magnetic field measurement unit. The shielding unit prevents external magnetic field interference, and the combination of the magnetic field and electric field measurement units improves the measurement accuracy.
This improves the stability and accuracy of power transformers, meets the measurement requirements of new power systems, and achieves higher measurement precision and accuracy.
